Which is the correct relationship btw equilibrium constants K1 and K2?

Question

(1) NO(g) + 1/2O2(g) <==> NO2(g)

(2) 2NO2(g) <==> 2NO(g) + O2(g)

A.) K2 = 2/K1

B.) K2 = (1/K1)^2

C.) K2 = -K1/2

D.) K2 = 1/(2K1)

E.) K2 = 1/(2k1)^2

Answer 1

reverse is inverse,...

&amp; K2 uses K1&#039;s [ ]&#039;s squared

your answer is : B.) K2 = (1/K1)^2
